A vulnerability has been discovered in SonicWALL GLobal VPN Client, which potentially can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to a format-string error when processing a VPN configuration file. This can be exploited by e.g. tricking a user into importing a specially crafted VPN configuration file with format-string specifiers in the "Hostname" tag or the "name" attribute of the "Connection" tag.
Successful exploitation may allow execution of arbitrary code.
The vulnerability is confirmed in version 188.8.131.526 and also reported in version 184.108.40.2060. Other versions may also be affected.
